CHARLES E. MURRAY, OF CHICAGO, ILLINOIS.

Application filed November 9, 1921.

To all whom it may concern:

Be it known that I, CHARLES EDWARD MURRAY, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Machinesfor Treating Bolts of Cloth for Clothing, of which the following is aspecification.

This invention to machines for opening and otherwise treating cloth asit comes from the mill in the usual longitudinally folded and rolledcondition, so that such cloth will be in condition for passage through asponging and shrinking machine by which the cloth is treated previous tobeing made into clothing; and the present improvement has for its objectTo provide a simple and eflicient structural formation and combinationof parts and mechanisms in which bolts or rolls of cloth in thelongitudinally folded condition in which they come from the mill, areopened, dry pressed, accurately measured during such opening andpressing actions, pleated upon a receiving table or platform, and thefinal sewing of adjacent ends of succeeding bolts of cloth is effectedwhen the pleating of one bolt of cloth is completed and the pleating ofa succeeding bolt has begun, so that a continuous length of cloth isobtained for passage through a cloth sponging and shrinking machine,such as forms the subject matter of my prior application for patent,Serial No. 470,546, filed May 18, 1921, all as will hereinafter morefully appear.

In the accompanying drawings Fig. 1, is a side elevation of a machineillustrating the general arrangement of parts in the present invention.

Fig. 2, is a detail plan view of the revoluble holder for the bolt ofcloth and the associated. pair of drawing rollers.

Fig. 3, is an end elevation of the machine.

Like reference numerals indicate like parts in the different views.

As represented in the drawings, the main supporting frame of the machineis formed with a base 1 and upright side standards 2, having rails andbrackets for the support of the parts and mechanisms of the machine.

Thedrawing rollers 13 are preferably adjustable to and from each other topermit the ready introduction of the cloth between the same as well asattain proper fractional engagement between the rollers and the cloth.To such end one of the rollers 13 is journalled directly in hearings inthe brackets 12 and receives positive rotation from driving connectionshereinafter described, while the other of said rollers 13 isjournalledin the free ends of radius bars 12' pivoted on said brackets 12. In thepreferred construction shown the shafts of the rollers 13 areoperatively connected together by intermediate gearing connections 14cof anysuitable type.

15 designates a platform of a triangular shape secured to the standards2 of the machine frame andin'clined downwardly towards the drawingrollers 13 with its point or apex adjacent to said. drawing rollers,and: preferably provided, with a centrally extending prong 16 adapted toenter between the double layers of cloth coming from said rollers toseparate said layers in the initial spreading of the same.

17 designates a shaft journalled transversely at the upper end of theplatform 15 and carrying a plurality of belt pulleys 17' in transversespaced relation.

18 designate a plurality of idler belt pulleys ournalled at therespective inclined sides of the platform 15 and adapted to support aplurality of carrier belts 19, by which the cloth is moved along theplatform in a spreading operation of such cloth.

designate a pair of positively driven carrier belts carried on drums 20journalled in the side frames 2 and arranged in an inclined position andon a plane with the carrier belts 19 of the platform 15. Said carrierbelts 20 are adapted to aid in moving the cloth through the machine.

21 designates a registering mechanism of any usual construction securedto side frame 2 and having operative connection with one of thehereinafter described shafts of the machine so as to register the travelof the positively driven carrierbelts 2O aforesaid. 22 designates adepending pendulum frame pivoted to overhanging bracket rails at the topof the side frames 2 aforesaid, and carrying at its lower end a pair offeeding rollers 23, to constitute the vibrating means whereby the clothas it leaves the carrier belts 20 aforesaid, is pleat-ed upon areceiving table or truck 26 arranged beneath said pleating means, asshown in Fig. 1. In the preferred construction shown, the pendulum framehas a fixed angle arm 22" through which it receives positive vibrationfrom the hereinafter described driving shaft of the machine. And thefeeding rollers 23 are preferably driven in a positive manner by beltand pulley connections with the above mentioned drawing mechanism, andwith a view to a ready insertion and removal of the cloth, one .of saidrollers is carried on pivoted links 24:, and yieldingly held in positiona spring 25, as shown. 2 designate horizontal rails 0n the side frame 2at the mid-height of the same and extending longitudinally beyond thepleating mechanism and receiving table above described.Iv I

27 designates a transversely arranged track connected to the outerportions of the rails 2 aforesaid, by hanger links 28, which arepreferably connected in a pivoted manner at their respective ends, sothat the track 27 may be swung out of the Way when not required for use.The track 27 is adapted to afford a supporting way for a transverselytravelling sewing machine by which the end of an already pleated roll ofcloth upon the receiving table 26 is sewed to the end of a succeedingroll of cloth being pleated upon said table, so that a number of rollsof cloth are connected in a continuous web for passage through asponging and shrinking machine, such as described in my aforesaidapplication Serial No. 470,546, in a further treatment of the clothprior to the making of the same up into clothing.

The series of shafts and connections by which simultaneous movement isimparted to the above described lllGCllitlllSlllS are mounted on themain frame and consists as follows 29 designates the primary power shaftof the machine, arranged transversely and receiving motion from anelectric motor 30 or other suitable power source.

33 designates a vertically arranged shaft having bevel gear connectionwith the shaft 29, so as to receive motion therefrom.

3 f designates a transversely arranged shaft having bevel gearconnection with the shaft 33 to rotate in unison therewith.

35 designates a longitudinally arranged shaft having at one end bevelgear connection with the shaft 34-, and at the other end like bevel gearconnection with the carrying shaft of one of the drawing rollers 13, toattain a positive drive of the same.

36 designates the shaft of the registering mechanism 21 having bevelgearconnection with the shaft 33 aforesaid.

37 designates a bevel gear connection between the shaft 33 and thetransverse carrying shaft 17 of the plurality of pulleys 17 and carrierbelts 19 thereon.

38 designates a pulley and belt connection between the shaft 17 and theshaft of one of the drums 20 of the pair of carrier belts 20 aforesaid.I

39 designate belt pulleys mounted loosely on the pivot shaft of thependulumframe 22, and forming an intermediate element of belt and pulleyconnections between the feeding rollers 23 of the pendulum frame and theshaft of one of drums 20 of the carrier belts 2O aforesaid.

In practical use the roll or bolt of cloth in the longitudinally foldedcondition in which it comes from the mills, is placed upon the revolublehead or platform t, with its respective ends engaged by the centeringblades 6 and 9 aforesaid, the folds of the individual layers or windings of the bolt or roll resting upon said platform 4i and thedisconnected edges of such layers in adjacent relation to the upper endsof the drawing rollers 13, and to the apex of the platform 15% and itsseparating prong 16. As so arranged the drawing rollers l3 acts to drawthe folded layers of cloth from the roll thereof and feed the same tothe separating prong 16 and the inclined platform 15 and its series ofcarrier belts 19, the action of which is to gradually open the layers ofcloth and present the same in a fully opened condition to the pair ofcarrier belts 20 to be measured and then passed to the pleatingmechanism heretofore described.
